Problems solved by technology

However, the electromagnetic radiation generated when the power carrier passes through the wire is relatively weak, coupled with the interference of external electromagnetic signals, the effect of directly detecting the radiation generated by the power carrier is often unsatisfactory, and it is also difficult to directly connect the detection device to the power line, resulting in The detection error of the radiation of the power carrier is very large, and it is not easy to accurately evaluate the radiation of the power carrier

Abstract

The invention relates to a power line carrier radiation detection device. The device comprises a first detection assembly; the first detection assembly can induct an electromagnetic wave frequency band radiated to the space by a power line carrier in a working state; the detection device comprises a first shielding body; the first shielding body is provided with a first shielding cavity; and in the working state, the first shielding body can shield electromagnetic waves radiated into the first shielding cavity in the specific direction of the space; the first detection assembly is arranged inthe first shielding cavity of the first shielding body; and a signal processing device is arranged in the first shielding cavity and comprises a PCB unit and a single-chip microcomputer. The device isconnected with a logarithm detection unit, and can be selectively provided with a low-noise amplifier and a filter so as to amplify original weak electromagnetic signals and improve out-of-band anti-interference capability, and therefore, the dynamic range of signal detection is expanded, and high-sensitivity and highly-dynamic monitoring of the radiation signals of the power line carrier is realized.

Description

technical field [0001] The invention relates to the technical field of power carrier radiation detection, in particular to a power carrier radiation detection device. Background technique [0002] Power carrier is a unique method in the power system. The realization of power carrier is the technology of high-speed transmission of analog or digital signals through the use of existing power lines. When power carrier is connected to terminal equipment, electromagnetic signals will be generated and transmitted through power lines. , and this electromagnetic signal will radiate to space through the power line. By detecting this radiation signal, the connection state of the power line can be evaluated. However, the electromagnetic radiation generated when the power carrier passes through the wire is relatively weak, coupled with the interference of external electromagnetic signals, the effect of directly detecting the radiation generated by the power carrier is often unsatisfacto...
